TO-aZZ whom it may concern..-

Be it known that I, JARVIS DAVIS, of the city of Buffalo and State. ofNew York, assignor to PA'rnIoK Snrrn, of the same place, have inventedcertain new and useful Improvements in Breech-Loading Rifles and I(lo-hereby declare that the following is a full and exact descriptionthereof, reference being had tothc accompanying drawings, nnikingapartof this specification, in which- Figure l is a side elevation of myimproved hreech-lmlding ritle. Fig. ']I is a top plan. l ig. IIIisalongitndinal section. Fig. IV is anlan ot' the s ding abutment ascoin-ierted to the guard.

Letters of like name and kind refer to like parts in each of thefigures.

The nature of iny invention relates, first,

to the. construction of a spring-hook, in combination with the lock of abreech-loading rifle, so-that when the rifle is tired the hook willCatch under the cartridge and draw the shell or case of the explodedcartridge out of the barrel and throw it oh when the gun is corked,second, in the construction of a slotted sliding abutment so combinedand an ranged that when the gun is tired the thin end of the cock-hammerwill pass through the slot and strikeand explode the cart-ridge, the

shoulders of the thicker part of the hammer striking against theabutment. and closing the slot.

' A represents the gun-barrel; B, stock; C, guard; I), lock; E, hannner,to which the spring-hook is attached. 1

F represents a hook, which-is hinged or completely jointed to the hammerat the butt-end thereof, as shown at f in Fig. III, the hook endprojecting forward of the hammer so as to pass un der the cartridge whenthe gun is fired.

' G"represents a spring, which is connected to the hammer by means ofthe screwh, the

free end of the spring lapping onto the buttend of the hook, so as tobear hard against it. The surface of the butt end, against which thespring bears, is made eccentric to the center or joint, so that when thehook is forced down alittle (as it is in drawing out the case oftheexploded cartridge) it will throw back the-spring, causing it topress with great forc thereon, and as soon as the cartridgeca-se isliberated from the barrel the spring guard to its position in the stock.

will react and throw the spring back U.- its place, in the hammer withsut'ticient force to throw oft the case of the exploded cartridge. Agroove is made in the hammer, in which the hook and spring are placed,and in which they act, as representedin Fig. III. A small recess orchamber-is made in the breech, as shown at '1', in order to allow thehook to pass under the cartridge and hook onto its flange.

J represents the sliding abutment. (The slottherein,isshownnt'j, Fig. lV.) .ltishinged to the guard as shown at C, so that the guard will moreit up and down, as desired. When the guard is dropped down to the po,sition ofthc dotted lines U", Fig. III, the abutment will be drawn downto the'position of the dotted lines J. and when the guard is thrown upto its place in the'stock, the abut ment will be carried up to its placein the in Fig. 111; then cock the gun; then put your cartridge into thebarrel and draw up the This brings the abutment up to its place in thebreech, ready for dircharge. not. discharged directly after loading, tlhammer should be letdown to lmfi'cock, where it may be handled withsafety. \Nhen the ritle is tired, the the thin end of the hammer passesthrough the slot in the abutment, nearly filling it, and strikes andexplodes the cartridge. The hook, at the same ti me passingin to thechamber 2',

hooks onto the cartridge, the shoulders of the hammer striking againstthe abutment. When the gun is discharged, the guard should beimmediately lowered, so as to draw the abutment to uncover the bore.Then it should he cocked, and in the actof cocking the hook I as hereindescribed.-
